[ICOM] PW1 and 10 meters

Thu Jun 21 16:06:30 EDT 2007

Tony,

No I was just chiming in as to what I read that appeared no changes had 
been made to the rules as shown on the ARRL web page.
Now though what I posted does not say, others write the wording has 
changed to allow for computer frequency control likely internal to the 
amplifier to control the amp operation below 28.000 MHz if I am getting 
it correctly.

A licensed amateur CAN modify his amplifier to operate on 10 meters. The 
FCC never stopped that as you pointed out.

So the existing Icom PW1, so far as I still know, needs to have a diode 
removed for that purpose. We were careful when the PW1 originally 
shipped how to offer that information to a purchaser due to the ease of 
modification wording in the rules. You have to play within the spirit of 
the law so to speak.
I will say the IC-4KL was real easy, just a undocumented switch.

I guess the question started why the PW1 was not shipping with 10 meters 
enabled and still required modification.
